1 Claim. (01. IZSbz-lfi) Our invention relates to index files as contained in ring binders, file folders, catalog binder-sand cabinets, and particularly to the type involving record sheets or cards mounted in cascading order, and one object is to provide a unit designed to support the record sheets to the best advantage.

A further object is to employ a series of anchoring devices. for the record sheets in'respect to a supporting sheet included in the novel unit,

such anchoring devices being manually applicable to mount or remove the record sheets with facility.

Another object is to construct the index unit with a self-contained support formed in a manner to permit groups of record sheets to be secured in placein succession as they are supplied or needed, and to be removable at any point in theseries.

An additional objectis to employ a securing device for the record sheets which enables them to be anchored to eachother throughout the series and secured tothe supporting sheet of the unit onryat desired points.

An important objecti'stodesign the novel unit along lines of extreme simplicity, in order to make its production economical and its use or handling easy for the average person.

With the above objects inview, and any others which may suggest themselves from the descrir tion to follow, a better understanding or the invention may be had by reference :to the accompanying drawings, in whichj Fig. l isa perspective view of a typical rin binder, showing the application of the novel unit;

Fig. 2 is an elevation showing the manner of mounting a series of record sheets in the, unit;

Fig. 3: is an enlarged view of the upper portion of, Fig. 2 from the right-hand side.

Fig. 4 is a top plan view of the showing in Fig. 2 on an enlarged scale and indicating a record sheet secured to the unit;

Fig. 4a is a similar view showing a pair of record sheets secured to each other and not to the unit;

Fig. 5 is a perspective view showing two modifications of the contents for the unit; and

Fig. 6 is a perspective view of an anchoring device.

The mounting of record sheets often occurs in ring binders, and th novel index unit is desi ned to facilitate such mounting. For-this purpose, the basic element of the unit is preferably a card indicated in the drawings at [0, such card havin the characteristics of a binder leaf,- such as the cloth hinge H and ring perforations f2.

rn o'rder to form the index unit, thebas card it receives a vertical sheet ['5' of thin cardboard,

such sheet'beingsecured to the basecard l-Oby a suitable adhesive. The sheet ['5 has a pair of side wings it which are bent-on folding lines: I 1 to project at an angle from the base'card' W. The wings H; are reinforced by being tucked between a-iolel t8- of cellophane or a-simiiar ton material, whereby tosti'itenthe wings; and the reinforcing wings are out with a-' vertical-series of perforations'zli. I

The sheet F5 is designed to serve-as a support fora series of record sheets as shown in Figs. 1 and 3, these being arranged in downwardlyeascadi'ng order to present visible index portions; and for the purpose of securing their support from the sheet F5; the record-sheets are formed with pairs of perforations -2 5- spaced'laterally and verti'callyas the supporting sheet perforations it.

Means for anchoring; the record sheets 2- 2 to each other and to the suppertingsheets" I 5 involve a strip 8i? of fihre, the end portions of the strip beingreduced in widthto-form-tonguest i which are pointed terminally at as, a clear illustration of such a strip occurrin in Fig, 6. The upper "riglrt-hancl= portionof Fig. 1 shows a single anchoringstri'pnearthe top secured with its tongues 34" passing through the wings F6 supporting sheet t5; Two anchoring strips are shown in succession a short distance below the ill-us tration just referredto, and-mounted in the same manner; and it will'be-noted -that the width'of the strips 36 is suchthat they abut along the contiguous edges when mounted in: succeeding perforations it or the-supporting sheet F5. This arrangement reinforcesthe stripsagainst angular deviation, and lends them smoothsurface asagroup.

The lower portion of Fig. 2 shows that a single record sheet is secured to the supporting sheet l5 by the application of an anchoring strip 30, first through the perforations 25 of the sheet 22, and then through the perforations 20 of the supporting sheet [5. It is noted that the lower pair of perforations 25 have been employed for the purpose just stated. Therefore, if the next record sheet 22 is to be mounted in upward order over the previous one, its anchoring strip 30 is made to pass through the upper pair of perforations 25 in the previous sheet before passing through the similarly located perforations of the supporting sheet IS. The second record sheet is thus secured not only to the supporting sheet but also to the first record sheet by the above operation; and the second advantage occurs in the stacking of the second anchoring strip 13 upon the first one for additional support.

Fig. 4 shows the manner in which the tongues 3| of the anchoring strip 30 pass through the record sheet and supporting sheet to a position in front of the base card 10. The backing function of the base card in respect to the tongues 3| prevents them from receding or creeping to loosen their anchoring hold, and the strips may therefore be considered as locked in place to hold the. record sheets 22 securely against vibrations or shocks suffered by the unit.

Fig. 4a shows the manner of anchoring the record sheets to each other, and not to the supporting sheet I5. In this case, it is expedient to procure such anchoring for the top and bottom record sheets in order to retain the series to the unit. This type of mounting is visible where the record sheets are light and designed for frequent removal, since it is easier to withdraw the anchoring strips where they pass through only the record sheets. However, such withdrawal is not diffioult in case more or all of the record sheets are secured through the supporting sheet I5. The simple application of the invention is shown in Fig. 1, involving a base of record sheet mounted on the unitary base card ID. A modified mounting is shown in the righthand portion of Fig. 5, Where the back cover 35 of a folder or blank book is employed as the base card. Where the record sheets are wide, as indicated in the modified showing, it is preferable to use two rows of anchoring devices, as indicated at 36 and 31.

A further modification of the invention is indicated in the left-hand portion of Fig. 5, where a cover 40 of a blank book serves the function of the base card It). Here, the record sheets are replaced by a set of pockets 4| adapted to carry food subject cards 42, the pockets having cutout portions 43 to disclose the indexing portions of the cards. Thus, a card index may be provided for the home to incorporate food information or recipes, with the pockets and cards changeable at will.

It will now be apparent that the novel index unit makes it possible to group many record sheets, cards, card pockets, or other indexing elements in compact form for easy identification and securely anchored to a backing unit forming a part of a loose leaf binder or blank book. Further, means are provided to securely anchor the index elements to each other and to their unitary support in any desired order, and to make such elements removable or interchangeable with ease. Further, the anchoring device employed inthe unit is simple, compact, and self-locking, so that the material supported in the binder or 4 blank book may be relied upon to hold its place as arranged or mounted in case of vibration or shock. Finally, the novel index unit is composed of few parts which may be fabricated by modern machine methods on an economical basis and for easy handling by the average person.

While we have described the invention and its modifications along specific lines, various minor changes or refinements may be made therein without departing from the principle thereof, and we reserve the right to employ all such changes and refinements as may come within the scope and spirit of the appended claims.

We claim:

A visible index unit comprising a base member, a retainer member comprising a central body portion rigidly secured to said base member, and a pair of oppositely disposed laterally extending wings foldable upwardly relative to said base member, each of said wings being provided with a series of perforations, each perforation in one wing being aligned laterally with a corresponding perforation in said other wing, a series of sheets, each of said sheets being provided with two vertically spaced pairs of perforations adapted to register with two adjacent pairs of perforations in said wings, and a pair of fastening members each having a body portion and a pair of end portions, one of said fastening members having its body portion overlying the portion of one of said sheets between the lower pair of perforations and having its end portions extending through said lower pair of perforations and through perforations in the preceding sheet and said wings aligned therewith, said other fastening member having its body portion overlying the portion of said first mentioned sheet between the upper pair of perforations and havings its end portions extending through said upper pair of perforations and through perforations in said wings aligned therewith, whereby each of said sheets is secured to said Wings at a plurality of vertically spaced positions.
